Like the title says I'm wondering which Anime you all were unsure/on the fence about watching but gave it a chance in the end and it turned out to be golden, like a very good Anime that maybe even became one of your favorites? Recent or old, any is fine

For me it was clearly "To be Hero X" (I do not know the prequel either lol), never heard about it before and the style change between the episodes made me really out off and unsure but in the end curiosity and boredom won. The music was also top notch and I'm waiting to see if it will get another season

Then there's "Link Click", it sounded interesting but I'm not too much into Donghua... I love it now and am on the edge of my seat each episode

Also "Mononoke", again I was unsure with the style bit it was soo good and now I want more (3rd movie just arrived on netflix)

There are even more but those are some I can think of right away
